SoHO à Cap Canaveral peu avant son lancement. L'Observatoire solaire et héliosphérique, en anglais Solar and Heliospheric Observatory, en abrégé SoHO, est un observatoire solaire spatial placé en orbite autour du Soleil.Son objectif principal est l'étude de la structure interne du Soleil, des processus produisant le vent solaire et de la couronne solaire. Soho (Solar and Heliospheric Observatory) est une mission conjointe de l'Agence Spatiale Européenne et de la NASA. Lancé en 1995, la sonde Soho est en orbite de halo autour du point de Lagrange L1 à 1,5 million de km de la Terre dans la direction du Soleil. De cette situation, Soho observe le Soleil 24H/24. La France a fortement participé The Solar and Heliospheric Observatory ( SOHO) is a European Space Agency (ESA) spacecraft built by a European industrial consortium led by Matra Marconi Space (now Airbus Defence and Space) that was launched on a Lockheed Martin Atlas IIAS launch vehicle on 2 December 1995, to study the Sun. It has also discovered over 5,000 comets. [2] SOHO's pioneering 25 years in orbit. The ESA-NASA Solar and Heliospheric Observatory (SOHO) is celebrating its twenty-fifth launch anniversary. Two and a half decades of scientific discovery is a major milestone for any space mission. But when the spacecraft at the heart of the celebration was only designed to last for two years, and operates The Solar and Heliospheric Observatory (SOHO) is a space mission that forms part of the Solar-Terrestrial Science Program (STSP), developed in a collaborative effort by the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA). The STSP constitutes the first "cornerstone" of ESA's long-term programme known as "Space Science — Horizon 2000".
